Abstract

This study aims to determine the types of wood used for making fishing boats and how to calculate the volume of wood needed for their manufacture in Olimoo'o Village and Kayubulan Village, Batudaa Pantai District, Gorontalo Regency. This study was conducted from March to September 2024 using a survey method. This study included measuring 50 boat samples, each sample divided into 25 boat samples in Kayubulan Village and 25 samples in Olimoo'o Village. The results showed that the types of wood used by boat craftsmen in making boats in Batudaa Pantai District, especially in the research location, namely Olimoo'o Village and Kayubulan Village, mostly used Nantu wood, namely from 50 sample boats, 17 boats used Nantu wood. Using Tindilo wood (5 boats), Wulu wood (7 boats), Wabo'o wood (6 boats), Binggile wood (5 boats), Talanggilala wood (5 boats), and Teak wood (5 boats). These seven types of wood are highly sought after by fishermen due to their high quality for boat construction. To estimate the wood requirements for boat construction, the plank volume and the length and diameter of the mahera were calculated using the plank volume coefficient (Cp), the mahera length coefficient (Cpm), and the mahera diameter coefficient (Cdm). The calculation results were Cp = 0.0525, Cpm = 0.9231, and Cdm = 0.7447.

Abstract

Tilapia is a fish species in Indonesia with significant economic value. Tilapia cultivation has excellent prospects, both domestically and internationally, requiring effective measures to ensure production meets community standards. The prospects for developing tilapia cultivation are quite promising, as the low production costs of tilapia farming allow for higher profits. Biofloc technology is an alternative solution to the waste problem of intensive farming. This technology is highly advantageous because it not only reduces inorganic nitrogen waste from leftover feed and feces, but also provides supplemental protein feed for farmed animals, thereby increasing growth and feed efficiency.This study aims to analyze the benefits and factors that influence the success of tilapia biofloc cultivation in SikoFish Gorontalo. This study uses a quantitative method with data collection techniques through surveys and observations. The results of the study indicate that tilapia biofloc cultivation can generate profits of Rp. 180,585,000 / harvest with a return on investment of 1.14 years. Factors that influence the success of tilapia biofloc cultivation are location selection, container preparation, media preparation, seed preparation, seed distribution, feed management, water quality management, and floc density. Therefore, it is necessary to develop business and production cost efficiency to increase income and make tilapia biofloc cultivation viable.

Abstract

Fase bulan merupakan faktor lingkungan alami yang memengaruhi distribusi ikan di perairan secara spasial dan temporal. Penelitian ini bertujuan untuk membandingkan komposisi dan kelimpahan ikan gobi di Sungai Bone Provinsi Gorontalo pada fase bulan gelap dan terang. Pengambilan sampel dilakukan di tiga stasiun sepanjang Sungai Bone Provinsi Gorontalo pada pukul 08.00 hingga 15.00 WITA. Waktu pengambilan sampel dilakukan pada fase bulan gelap dan terang masing-masing pada 1 Dzulhijjah 1446 Hijriyah (bulan gelap) dan pada 13 Dzulhijjah 1446 Hijriyah (bulan terang). Hasil identifikasi menunjukkan terdapat 9 spesies ikan gobi pada bulan terang dan 8 spesies pada bulan gelap, dengan Sicyopterus longifilis sebagai spesies dominan. Hal ini mengindikasikan bahwa komposisi dan kelimpahan ikan gobi di Sungai Bone Gorontalo dapat saja dipengaruhi oleh fase blulan. Namun berdasarkan uji korelasi non parametrik Spearman, tidak terdapat hubungan antara fase bulan dengan jumlah individu maupun kelimpahan relatif ikan gobi di Sungai Bone

Abstract

This study aims to assess the diversity, evenness, and dominance of gastropods in dead coral habitats, as well as the current environmental condition of the waters around Lahe Island, Pohuwato Regency. The research was conducted in April 2025. Gastropod sampling was carried out using the hand-picking technique during low tide conditions, employing a belt transect method measuring 50 × 3 meters across three observation stations. Water quality parameters were measured during the early stages of tidal retreat. Based on the results, gastropod species composition consisted of 34 species, 185 individuals, and 12 families (Buccinidae, Columbellidae, Conidae, Cypraeidae, Mitridae, Muricidae, Nassariidae, Pisaniidae, Strombidae, Tegulidae, and Turbinidae). The Shannon diversity index (H’) at all observation stations was < 2, indicating low diversity. The Simpson dominance index (D) at all stations was < 1, suggesting a high level of dominance. The evenness index (Ep) showed values approaching 0, indicating low species evenness. The water conditions around Lahe Island, Pohuwato Regency, indicate a moderate level of pollution based on the Shannon diversity index (H’), yet still support the survival of marine biota.

Abstract

This study aims to analyze the marketing chain of skipjack tuna (Katsuwonus pelamis) caught by pole and line vessels at Belang Port, Southeast Minahasa Regency. The research method used is a survey with a descriptive approach, involving fishers, middlemen, and retailers as respondents. Primary data were obtained through interviews, observations, and documentation, while secondary data were collected from relevant literature. The results show that the marketing chain of skipjack tuna involves three main channels: (1) zero-level channel (fishers directly to consumers), (2) first-level channel (fishers to retailers), and (3) second-level channel (fishers to middlemen and then to retailers). The highest marketing margin is received by retailers, while the lowest is received by fishers. Marketing efficiency is influenced by several factors, including limited capital, infrastructure, market information access, and the dependence of fishers on middlemen. This study recommends strengthening fisher institutions, improving market access, and providing training and empowerment in marketing to enhance efficiency and the welfare of fishers.
